How do I find out what applications are running in the background
I have a 2008 iMac with 2GB memory. How do I find out what programs are running in the background? I am going to buy a new iMac before the end of the year to replace this one. When I looked at Activity Monitor it shows 1.8Gb used but doesn't tell all the programs running.
open activity monitor [if it doesnt launch click winders>Activity Monitor]. then it'll show all proceses

How do i see what applications are running in the background
My iMac is running very slow my operating system is OS X Yosemite Version 10.10.2 with a 2.5 GHz Intel Core i5 Processor. How do I see what applications are running in the background?
Reinstalling OS X Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Reinstalling OS X Without Erasing the Drive
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility and press the Continue button. After Disk Utility loads select the Macintosh HD entry from the the left side list. Click on the First Aid tab, then click on the Repair Disk button. If Disk Utility reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit Disk Utility and return to the main menu.
Reinstall OS X: Select Reinstall OS X and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
Alternatively, see:
Reinstall OS X Without Erasing the Drive
Choose the version you have installed now:
OS X Yosemite- Reinstall OS X
OS X Mavericks- Reinstall OS X
OS X Mountain Lion- Reinstall OS X
OS X Lion- Reinstall Mac OS X
Note: You will need an active Internet connection. I suggest using Ethernet
if possible because it is three times faster than wireless. -
my macpro runs slow with or without internet on..... How can I find out if something is running in the background?
Please boot in safe mode and test. Still slow? If you connect to a wireless network, you may have to connect with Ethernet in safe mode.
After testing, reboot as usual (not in safe mode.)

How do i find out what devices are authorised on my apple ID?
I have just bought a new iMac and want to get all my itunes library etc on it. However, apparently i have reached my limit of 5 authorisations, which is entirely possible as I have had a number of iphones, Macair and ipads, some of which I either no longer own or are no longer functioning. How do I find out what devices are authorised and then deauthorise any that I don't use any more - given that they may not even work!
Welcome to the Apple Community.
You can't de-authorise just the computers you no longer have access to.
Your only option is to de-authorise all your computers and then re-authorise those you wish to be authorised. You can do this by logging into your account settings in iTunes on your computer (Store > View My ID) and selecting the option to de-authorise all.
Please note however, you are only permitted to do this once in each 12 month period, therefore you would be better de-authorising your computers before you lose access to them. you can do this from the 'Store' menu in iTunes. -
How do i find out what drives are present in a particular system
Hi,
How do i find out what drives are available in a particular system either by giving the systems ipaddress or the systems name...You can't do that. That would be a real security risc.

How do I find out what features are not useful in my Classifier?
How do I find out what features are not useful in my Classifier? I am trying to trim down the number of features to speed up the training of my data, I have about 3700 features. I have found the Filter Based Feature Selection Module and have not been successful
in using it. I have looked through all the examples and have not been able to find any examples using the module. Will the Filter Based Feature Selection Module help me to trim features. If so how do I use it?One way to do this would be is to use a random forest classifier. Feature/variable importance can be obtained relatively easily with random forests.
Here is how you may do it in R.
> install.packages('randomForest') #install randomForest package in R if it is not already there
> library(randomForest) # reference the library
> data(mtcars) # load motor cars data that ships with
#train a random forest
> mtcars.rf <- randomForest(mpg ~ ., data=mtcars, ntree=1000,keep.forest=FALSE, importance=TRUE)
> importance(mtcars.rf)
> importance(mtcars.rf)
#You will see an output like below

# or plot the importance as follows
> varImpPlot(mtcars.rf)
What this tells you is how important predictors/features/variables like horsepower(hp), weight(wt), no. of cylinders (cyl) is in predicting miles per gallon (mpg).
If you are wondering how the data looks like. Try this
head(mtcars) # gives first few lines of the data set.

Oh, then you can't unless you know someone with a Mac you could use for a moment or 2. (Like at the Apple Store) -
How can I find out what apps are on my step daughters phone without the phone?
How can I find out what apps are on my step daughters phone without the phone? She is on my phone plan but does not live with me and I am concerned about the apps she may be using.
baniville108,
Thank you for reaching out to us. We certainly know the importance of being able to know what options are available with your device. With apps on devices, thoses are specific to the phone itself, so there is no open forum to view what apps are downloaded. The only option would be to physically review from the phone, or if you have the same Apple ID you can log into it and view from there. Please let us know if you need anymore assistance.
Thank you,

I have three charges on my credit card from apple, same day and same amount. How do I find out what these are for?
You should receive an email receipt for any purchase (though it may not appear immediately, mine sometimes appear the following day).
You've checked the purchase history on your account (Store > View My Account, Store > View My Apple ID on iTunes 11, menu option on your computer's iTunes), and have you made any in-app purchases ? If not and you haven't added or changed your credit card details (when you do then a small temporary store holding charge may be applied to check that the details are correct and valid, which should disappear within a few days) then you could contact iTunes Support and ask if they can help : http://www.apple.com/support/itunes/contact/ - click on Contact iTunes Store Support on the right-hand side of the page, then Purchases, Billing & Redemption
